Seedling
2-3 weeksSmall seedlings with 2-4 true leaves emerge. Seeds germinate slowly over 2-3 weeks.
Keep soil moist but not soggy. Provide bright indirect light. Thin seedlings to proper spacing once they have 2-3 true leaves.
Vegetative Growth
4-8 weeksPlant develops multiple stems and increasingly divided, dark green flat leaves. Bushy growth pattern forms.
Begin light harvesting once plant has 6+ leaves. Pinch out flower buds to encourage leaf production. Keep soil consistently moist.
Established Growth
Ongoing for 3-4 monthsMature plant reaches 12-18 inches tall with abundant dark green foliage ready for regular harvesting.
Harvest outer stems regularly to promote bushier growth. Consistent harvesting delays bolting. Fertilize monthly with balanced fertilizer.
Flowering/Bolting
4-6 weeksPlant sends up tall flower stalks with small white or pale yellow flowers in umbrella-shaped clusters (umbels).
Remove flower stalks to extend leaf production if continued harvest is desired. If saving seed, allow flowers to mature.
Seed Production/End of Season
4-8 weeksFlowers give way to small, brown, ribbed seeds. Foliage becomes coarser and less palatable.
Allow seed heads to dry on plant if seed collection is desired. Otherwise, remove plant at end of season.

Harvest Tips
Begin harvesting when plant has at least 6 leaves (typically 6-8 weeks after planting). Pinch or cut outer stems first, working toward the center. Harvest in the morning for best flavor and oils. Regular harvesting encourages bushier growth and delays flowering. The entire plant can be harvested if needed. Leaves are best used fresh but can be dried or frozen.
